BLANK 6A5 comp/amt INVENTOK QAZZLM S /W TREW', DETBQIT CHINE Application filed July ing machine and has special reference to the tahulating equipment of such machine, which equipments usually comprise a laterally shittalole paper carriage with suitable means for controlling the columnar positioning of the same.

The principal object of my present inven- 10 tion is to betteradapt the tahulating equipment of an adding and'listing machine to the handling of various work sheets such, "for example, as led er sheets, hills, record or proof sheets, and. the like. Among other more specific objects of my invention ace the provision of means for automatically tilting the platen carrying frame when the paper car riagre is moved to a predetermined columnar position, to facilitate the insertion in andre moval "from the paper carriage of some of the work sheets, while the platen frame is latched in its tilted condition, the employment of means for disabling such tilting device, and the provision of improved means for supporting the worn sheet on the paper carriage in the proper or desired printing position and for readily accommodating work sheets of different sizes.

Vith the above and incidental objects in view the invention consists in certain novel features of construction and combination of parts, the essential elements whereof are re cited in the appended claims and a preferred form of embodiment of which is described in detail hereinafter and illustrated in full in the accompanying drawings which form part of this specification.

The invention herein shown is applied to the well-known Burroughs adding and listing machine,- but it is to be understood that it is not limited necessarily in its application thereto. For the sake of illustration and convenience, but without limitation thereto, I have also shown and will describe my invention as being peculiarly adapted to handle the the extent of movement of the usual actuating levers which carry type plates 1 for presenting the items and totals to the printing line, racks being carried at the forward ends of the levers for actuating the usual adding and subtracting registers. A back panel 2 of the supporting framework of the machine has secured to it the usual track 3 upon which the laterally shiftable carriage 4 runs. A rotating platen 5 is supported in a rocking frame 66 mounted on a cross-rod 7 carried by the carriage 4. This platen frame 66 also carries a paper support or back 8 (Figs. I, II, III and V) for guiding the proof or record sheet, such as sheet P, shown in Fig. XXIII. Laterally adjustable guides 9 are slidably mounted on the back 8, being provided with lock nuts and bolts 11 with the bolts extending through slots 10 in the back 8, as shown in Itinsche Patent No. 1,208,375, granted December 12, 1916, to which reference may be had with respect to this and certain other well known features of the Burroughs carriage equipment.

Also mounted on the paper carriage 4 is a rock shaft 12 (Figs. I and II) carrying the customary series of column stops or dogs 13 for determining the columnar position of the carriage. On each operation of the machine, when the carriage is moved from right to left (as viewed from the front) from one columnar position to the next by the carriage spring 14 (Fig. I), releasing mechanism 15 is operated by a cam 16 through the lever 17 to rock the shaft 12 and thereby move one of the stop dogs 13 out of engagement with a permanent stop 18, the shaft 12 being rocked back to normal position by 'a spring 19 through a lever 19 and arm 19, so that the next stop abuts the permanent stop 18 to arrest the carriage in: the next columnar posi tion, all of which is the usual construction and operation in Burroughs machines.

The machine is operated by an electric motor 20 through suitable connections, the motor and connections being substantially the same as those disclosed in Patent No. 866,750, issued September 24, 1909, upon an invention of Jesse G. Vincent,to which reference may be had for a more detail description of the same. Suffice it to say here that, when the touch or finger bar of that patent is depressed by the operator, the motor clutch is rendered effective, whereupon the drive shaft is given its positive stroke by the motor through a crank arm 21, a link 22 and an arm 23, the drive shaft being returned to its normal position bythe customary power springs 24.

As an incident to the operation of the machine, when the carriage is in its last columnar position (i. e., its extreme left-hand position) it is returned toward the right to its first columnar position by the motor 20 through suitable connections such as those shown and described in Rinsche Patent No. 1,580,534, to which reference may be had for a more detailed description of the same. It will be sufficient to but briefly describe this mechanism here. shaft 25 (Fig. I) carried by a vertical housing 26. An irregular shaped housing 27 is secured to the upper end of the housing 26 and a gear (not shown) is secured to the upper end of the shaft 25 which extends into the housing 27. This gear meshes with a gear 28 (Figs. XIV and XV) journaled on a stud 29 suitably supported in the housing 27. On the upper end of the stud 29 is journa-led a gear 31 meshing with a rack bar 32 (Figs. III, XIV and XV) on the paper carriage 4. Upon normal operation of the machine when the carriage is shifted from right to left, as viewed from the front of the ma- ,chine, by the carriage spring 14, the rack 32 being moved with the carriage rotates the gear 31 which is normally disconnected from the gear 28; but when the machine is operated with the carriage in the last columnar position, the gears-28 and 31 are automatically coupled together by a clutch mechanism, designated generally by the reference numeral 31", whereupon the gear 31 is rotated in the reverse direction by the electric motor to return the carriage to the first columnar position in opposition to its carriage spring 14. The clutch device 31 and its operating lever 39 are the same as that disclosed in tho 1 aforesaid Patent No.,1,580,534 and it will be The motor 20 drives a L as viewed in Figs. XIV'and XV) with a vertical extension which is adapted to engage one end of a sliding bar 34, as the carriage moves slightly toward the left (as viewed from the front) past its last columnar position upon operation of the machine with the carriage in such position, and the bar 34 is thus slid from the position shown in Fig. XIV to that shown in Fig. XV. The bar 34 is guided in its sliding movements by studs 41 and 44 on a plate 43 engaging in slots 42 and 45 in the bar 34. Due to its irregular shape, the bar 34 extends over the supporting plate 43 so that portions of the bar are on opposite sides of the plate 43. An offset downward projection 46 on the bar 34 62(- tends over and in front of the plate 43 to assist in guiding the bar 34 in its sliding movements. A latch 35 is pivotally mounted at 35 on the bar 34 at a point above the slot 45, and the latch 35 is normally held in the position shown in Fig. XIV by a stud 36 against the tension of aspring 37 connected at its ends to the bar 34 and latch 35. In this normal condition of the parts, the clutch lever 39 is held in its clutch disabling position by a stud 40 which engages the upper of two notches 51 in the clutch lever, the stud 40 being carried by a latch arm 50, held in latching position by its spring 52. As the carriage moves slightly past its last columnar position, the stop 33 slides the lever 34 to the position shown in Fig. XV, as above stated, whereupon the latch 35 is raised by its spring 37 when a notch 35 in'the latch comesunder the stud 36. This rocking movement of the latch 35 results in an upper edge 35 of its extension engaging a stud 38 on the clutch lever 39, thereby rocking the lever 39 to throw in the clutch 31 and cause the gear 31 to rotate with the gear 28 and thereby move the carriage toward the right (as viewed from the front) to its first columnar position. In Fig. XV, the stud 38 is shown slightly above the edge 35 but this is due to the fact that the stud 40 seats itself in the lower notch 51 of the latch. arm 50 and raises the one end of the lever 39 a little further than it is raised by the latch 35.

When the carriage is moved by the electric motor from itslast columnar position toward the right, as viewed from the front of the machine, the carriage is moved slightly past the first columnar position and during this additional movement the clutch 31 is disabled by the following described mechanism to permit the carriage to be moved slightly back to its first columnar position by its spring 14. As bestshown in Fig. XVI, a clutch releasing finger 204, having a cam face 205, is adjustably mounted on the left-hand end (as viewed from the front) of the rack bar 32. This finger has an offset extension 208 in line with an extension 35 on the latch 35. When the carriage moves slightly past its first columnar position, as above stated, the offset 208 engages the extension 35 thereby first rocking the latch 35 about its pivot 35 to carry the notch 35 in the latch away from the stud 3b and the edge 35 away from the stud 38 and then slide the bar 34 to normal position. During this sliding movement of the bar 34, the cam edge 205 of the linger 204 engages over a roller stud 206 on the clutch lever 39, thereby rocking this lever from the position shown in Fig. XV to that shown in Fig. XIV to release the clutch 31 and hence disconnect the gear 31 from the gear 28, whereupon the carriage spring 14 moves the carriage slightly back toward the left to its first columnar position. The clutch lever 39 is then retained in its normal position by engagement of the stud 40 on the latch 50 in the upper notch 51 on the clutch lever.

In machines to which my invention is preferably applied, the performance of the machine with respect to the registering and re cording functions, when the paper carriage is in its different columnar positions, is dctermined by elements on the paper carriage through suitable connections such as fully shown and described in the Muller Patent No. 1,379,774, granted November 22, 1921. As this mechanism is not essential to the understanding of my invention it is not shown or described in the present drawings and specification. Sufiice it to say here that control rollers B. (Fig. I) are carried by the carriage and operate control levers A which in turn control the various operations of the recording and registering mechanisms, in order that the machine will properly function in its various columnar positions to perform the class of work for which it is intended.

Emamples 0,?" work.

Before proceeding to describe the features of the machine constituting my invention, it may be well to describe briefly the operation of the machine in connection with the printing on work sheets, such as shown in Fig. XXIII for illustrative purposes. When the ledger sheet L, the hill 3 and the proof sheet P and its carbon C, are inserted in the paper carriage, as will be described later, the paper carriage is in its second columnar position and at this time the platen carrying frame is tilted back b0 facilitate the insertion of the ledger sheet and the bill. For convenience the columnar positions of the carriage will be considered as being numbered from right to left, the extreme right-hand position being treated as the first columnar position. N 0 entry is to he recorded on the ledger sheet 11 while the carriage is in its second columnar position so that the machine is operated after the platen frame is rocked back to normal position, to permit the carriage spring 14 to move the carriage to the third columnar position. In carrying out the present example, I

I the operator now sets up on the keyboard the prior reading 111, the present reading 222, and the consumption 111 cu. ft, it being understood that the machine is split so as to avoid one number running into the other, or in other words in order to separate the numbers. Upon operation of the machine the'present reading 222 i and consumption 111 will be printed on the ledger sheet, but the previous reading 111 will not be printed because of it being hammer blocked, it being preferred not to print this previous reading as it already appears as a previous item in the column above the recorded present reading. The carriage then automatically shifts to its fourth columnar position and the printing mechanism is controlled by one of the rollers R and the machine is again automatically operated to print the three items 111, 222 and 111, on the bill B while the carriage is in the fourth columnar position. These same items are printed on the proof sheet P through the carbon C. The carriage automatically shifts to the fifth columnar position and then the operator sets up the customers folio number and operates the machine to print this folio number in the code column on the proof sheet through the bill and carbon, but this folio number will not be decipherable on the bill as it is printed on a heavy black imprint block d on the bill. The carriage now automatically shifts to the sixth columnar position and the operator set up the monetary items, for example, $5.00,

$4.00 and $9.00 and depresses the touch bar to operate the machine. These items are printed on the bill and also on the proof sheet,

unmar position and effect operation of themachine to repeat print all three items, $5.00, $4.00 and $9.00 on the stub of the bill, but as there is no carbon back of the stub the items will not be printed on the proof sheet while thecarriage is in such position. At the .end

carriage will tabulate to the second columnar position, which is shown in Fig. II. It will be observed that the first columnar position of the carriage is really the one in which the last printing operation is performed to complete the entire entry of the transaction.

.. nreaeee Platen frame tilting device.

The mechanism for tilting the platen carriage when the carriage is in its second columnar position is one of the features of my present invention and will now be described, reference being had more particularly to Figs. V, VI, IX, X, XII and XXH. The side plates 6 and 6 of the platen frame are braced by a square cross-rod 53, as is usual in Secured to this cross-rod is a tilting cam plate 54 so positioned that when the carriage is moved from its first to its second columnar position, the plate will ride under a roller stud 64, normally in its path, with the result that the platen frame is tilted rearwardly from the position shown in Fig. V to that shown in Figs. VI and IX, in order that both the bill B (Fig. VT) andthe ledger sheet L (Fig. X) may be readily dropped into position in front of the platen without interference from the platen or the necessity of feeding them into position by means of pressure rolls. N ear the end of the movement of the paper carriage from its first columnar position to its second, the cam plate 54 moves out of engagement with the roller stud 64 but the platen frame is then latched in its tilted position by means of a latch 105 (Fig. IX) as will be described later. The camplate 54 has supporting end pieces 55 and 56 (Figs. X and XXII) hav ing square recesses to embrace partially the square rod 53 and in order to retain the cam plate in its predetermined position on the rod 53 locking washers 57 are provided. The washers are provided with threaded holes to receive screws 58 (Fig. XXII) extending through the end pieces 55 and 56 and are also provided with square notches having their opposite sides beveled reversely as indicated at 55 so that they may be readily inserted over the bar 53 angularly, as illustrated by the dash-dot lines in Fig. XXII, and then straightened and moved against the side plates 55 and 56 to which they are secured by the screws 58, the sharp edges, formed by the beveled sides then binding on the square rod 53 sufliciently to prevent longitudinal displacement of the cam plate 54. It will be obvious that when the bolts or screws 58 are loosened, to permit tilting of the washers 57 the cam plate 54 may he slid to any position on the rod 53 so that the platen frame will be rocked rearwardly upon movement of the paper carriage to the Selected columnar position, determined by the character of the work to be performed.

The roller stud 64, for tilting the platen frame by its coaction with the cam plate 54, is mounted on the free end of an arm 61 Figs. XII and XIII) and is held in place thereon by a shouldered nut 65 the reduced portion of which is free to move in an arcuate slot 66 formed in a plate 59 supported on the back 43 by bolts ell and 69 (Fig. 3 c 59 being spaced from the plate pivotally supported in bus U n the plate 59 is held irom displacement by a ..eaded screw The roller stud 64 and"its arm '61- are non really held in their upper active position by a spring 6?

suitable spacing collars 1s Paper guide chutes.

In addition to the paper table 8, for supporting the proof sheet P and its carbon as above stated, the paper carriage 4 is provided with another paper guide or plate 71 (Figs. Ill, V, VI, XI and X) which extends above the platen and has its lower portion curved to extend partially around the front of the platen. This guide plate is provided at its ends with rearwardly extending lugs 7 4 (Fig. IX) which are connected by screws or otherwise to the side plates 72 and 7 3 rigidly secured by screws 74 to the carriage 4. cross-rod 75 is supported in rearwardly extending lugs 72 and 73 (Figs. IX and X) on the side plates 7 2 and 7 3, and mounted on this rod is a paper guide finger 76 (Figs. III and V) which acts to guide the bill toward the front of the platen. This guide finger is supported on the cross-shaft 75 by rear- Wardly extending lugs 76 and 7 6", and is held against longitudmal displacement by a friction spring 77 and against rotational movement by a spline on the rod 75. Also mounted on the cross rod 75 near its opposite ends are paper guides or chutes 78 and 79 (Figs. III and V) which. are also prevented from moving longitudinally by springs similar to the spring 77. These paper chutes 78 and 79, as shown in Figs. III and X, are .open at their inner sides and are flaring at the top and somewhat contracted at the bottom. The 65 front walls of the chutes 78 and 79 are entering the chute 80, will be inserted baclr A and by coaction with pressure rollers 90, the

In some cases the bin -nay be somewhat longer than the available distance between the chutes 78 and 80, as when exceedin ly long advertising stub is attached to the bi, in which case one end-of the bill is inser'ed in the chute 78 and the other end, instead of this chute and part of the ledger sheet and as no carbon is used with the ledger sheet the printing on the overlapping portion of the latter will not appear on the advertising end of the bill.

Pressure rollers and paper pan for proof sheet.

The proof sheet P and the carbon paper (Figs. V, VI, X, and XI) through which the items are printed at the proof sheet. are placed on the table 8 and are guided by the pre-set paper guides 9, when they are fed around the platen upon rotation of the latter forward end of the proof sheet and carbon being guided by a floating pan 92 and well known guide fingers 91, supported at their upper ends on a cross-rod 91 and having their forward lower edges offset to slightly overlap the upper front edge of the floating pan 92.

As shown in VII, each pressure roller 90 is supported on a pair of arms 93 which are notched to fit a shaft 94 and which have the customary extensions 95 engaging flattened portions of the pressure roll control shaft 7. Immediately adjacent and inside of each side arm 93 is another arm 96 also notched to fit the shaft 94. The pressure rolls 90 are yieldingly pressed against the platen b means of springs 97 which encircle the sha t 94, and have their forward ends engaging in holes in projections 96 on the arms 96 and their other ends underlying v the width of the platen and its upper rear corners rest against offset lugs 98 on the side braces 99 which support the paper table 8 at either side and which themselves are securely fastened to the square cross shaft 53 by ofiset lugs and screws 100, as best shown in Fig. VII. In order to yieldingly support the floating pan 92 and retain it against longitudinal displacement beneath the platen, the pan on its under-side has securely attached thereto two inverted Iii-shaped brackets 101 (Figs. IV, V II and VIII whose downwardly extending projections are slotted to engage annular recesses 102 in the cross-rod 94. Riveted to the horizontal parts of the brackets 101 are leaf springs 103 whose free ends seaton the oilset lugs 86 (Fig. IV) of the pressure roll engaging members 90, the springs being bent downwardly towards their free ends to such an extent as to create a tendency to force the floating pan against the platen. At each end of the floating pan 92 leaf springs 104. ig. IV similar to the springs 103, are securely fastened and the free ends of these springs likewise engage offset lugs '96 to assist in holding the floating pan in yielding contact with the platen. N hen the shaft 7 is rocked to move the rollers 90 out of engagement with the platen 5, the forward ends of the levers 96 are lowered thus relieving the tension of the springs 103 and 104.

This manner of mounting the pan affords v expeditious insertion of the proof sheet and carbon and prevents the carbon from buckling or bending as is very often the case in the usual form of floating pan without the yielding supporting means.

Latch for platen frame.

latch. The rear end of the horizontal arm of the latch has a notched shoulder 110 which,

when the platen frame is tilted back, as above described, engages a shouldered stud 110 on the right side plate 6 of the platen frame and is retained in said latching condition by a spring 111. It will thus be seen that when the platen frame is locked in its tilted position, shown in Fig. IX, the latch may be operated by the linger-piece 109 to move the shoulder 110 away from the stud 110*, whereupon the sprin 112 (Fig. II) common to Burroughs machines, will rock the platen frame forwardly to its normal position, in which the platen presses the bill and ledger sheet against the lower curved portion of I the paper guide 71. In order to prevent the platen frame from rocking forwardly to its normal position with a jar when thelatch is released, a brake lever 113, mounted on the pivot 106, is provided. The under edge of the rearwardly extending arm of the lever 113 is so positioned with respect to the shouldered stud that when the platen frame is rocked forwardly upon release from the latch 105,the stud 110 engages this lower edge thereby rocking the lever 113 counterclockwise from the position shown in Fig. IX to that shown in F I, against the action of a spring 114 connected to the down wardly extending arm of the brake lever. The clockwise movement of the lever 113, when the platen frame istilted rearwardly, is limited by engagement of a stud 115 on its downwardly extending arm against the side plate 72. In case the spring 111 fails for any reason to move the latch 105 to latching condition when the platen frame is rocked rearwardly, an ofiset lip 113 on the brake lever 113 and projecting over the top of the latch 105, will lower the latch to latching condition, when the spring 1145 rocks the brake lever 113 to the position shown in Fig. IX,

Bill and ledger sheet pressure rollers and if support therefor.

When the bill and ledger sheetareinserted into the machine, with the platen frame in its tilted condition, the lower edges of the bill and ledger sheet are dropped onto adjustable stops or shelves (to be described presently), which have been pre-s'et so that the items will be printed on the desired horizontal printing lines on the bill and ledger.

These supporting devices are carried by a plate or table 117 (Figs. V, VI, X, XI and XVIII) which is secured by screws 118 to the paper carriage 4 and which extends substantially tangential to, the platen and is so positioned that it forms, in efiect, a continuation of the front guide plate 71. As shown in Fig. 18, the upper corners of the plate 117 are provided with rearwardly extending lugs or ears 119 secured to the side plates 72 and 73 by screws or otherwise.

Equally spaced along the upper edge of in the plate 117 and the plate 124 is provided the plate 117. Springs 122, having portions encircling the hinge pins, serve to hold the rollers 121 against the platen.

Supporting and collating mechanism for hills.

As best shown in Figs. XVIII and XIX, the plate 117 has parallel guide slots 123 through two or" which extend studs 125 having coiled pressure springs which serve to yieldingly retain a plate 124, through which th studs project, in adjusted position on the plate 117. A finger-piece 126 is slidably secured to the plate 124 and terms a fingerhold whereby the plate 124 may be moved up or down to the desired position. The finger piec 126 is provided with screws 124 (Fig. 5} and flanged nuts 124 which extend through slots 123 in the plate 117 to permit adjustment of the plate 124, the carriage being provided with a groove 128 to accommodate the nut 124 Secured to the plate 124 in line with the slots 123 are spring shelves or finger supports 127 in the form of Ushaped leaf springs which act as supports for the lower edge of the bill. The free ends of these spring supports are normally positioned in the slots 123, as shown in Fig. VI, but when the plate 124 is moved near its upper limit of movement, so that the lower part of the bill will be printed on, the spring supports 127 strike the floating pan 92 bending the spring supports forwardly so that their free-ends project beyond the slot, as shown in Fig. XI thus preventing injury to the supports. The carriage 4 is slotted or grooved at 128 in line with these fingers to permit this movement of the finger supports. These grooves 128 also accommodate the heads on the lowerends of the spring-pressed bolts 125. In order to retain the plate 124 in any of its set positions, series of depressions 136 are formed with punched projections 137 adapted to en- I gage in the depressions 136.

A modified form of bill support is shown in Figs. XX and XXI. It preferably consists of hinged plates 149 suitably arranged along the top edge of the plate 124 and pressed upwardly in the direction of the platen by suitable springs 150, having portions coiled about the hinge pins for the plates. The hinge eyes of the plates 149 are provided with cut-out shoulders 149 adapted to engage projections on the upper edge of the plate 124 in order to hmit the upward movement ofthe plates 149. I

Supporting and collating mechanism for ledger sheets.

As the ledger sheets are quite long, an auxiliary guide plate 129 (Figs, XVIII and XIX) is mounted on the plate 117 for guiding the lower portion of the ledger sheet and for carrying an adjustable device 133 which supports the ledger sheet at the desired printing line. This auxiliary guide plate 129 is connected to the plate 117 by bolts and nuts 130, and the bolts extend through a horizontal slot 131 in the plate 117 to permit longitudinal adjustment of the auxiliary guide "plate 129 so that the ledger sheet will be centrally supported on a supporting device 133 carried by this auxiliary plate. Two vertical slots 132 having beveled edges, are provided inthe plate 129. The ledger sheet support 133 is provided with spring-pressed bolts 134, having conical heads 135 (Fig. which engage the beveled sides of the slots and do not project beyond the plate 129 thereby permitting the support 133 to be moved above the lower edge of the plate 117, which movement would be prevented, due toengagement of the projecting heads of the bolts against the lower edge of the plate 117 if the heads projected beyond the plate. The ledger sheet support 133 comprises the two end plates 138 and the integral connecting piece. Each end plate 138 has projections 139 and 140 extending forwardly into the slots 132 to aid in guiding the support durledger sheet support 133 in its adjusted or set position. Finger-pieces 143 project from the connecting portion of the support 133 by means of which the operator moves the support to the desired position. The depressions 136 for the bill support and the depressions 141f0r the ledger support are so spaced that for single-space work the supports 124 and 1 33 may be adjusted a distance equivalent to two depressions for each single space on the bill or ledger sheet.

In order to guide the ledger sheet onto the supporting device 133, a guide plate or strip 145 is secured at its lower end to the lower end of the auxiliary guide plate 129, the guide strip 145 bein suitably spaced from the plate 129 and parallel therewith in order to guide the lower edges of the ledger sheets onto the support and also prevent displacement therefrom.

long bills would'be inserted into the machine by dropping one end into the chute 78 and Another guide-plate 146 is secured near the upper end of the guide strip 145 IOU - entries on the various work sheets.

the central portion back of the chutes and 81 and the other end into the space 1 18 between the guide plates 145 and 146.

Resume.

It will now be obvious that when the carriage is in its second columnar position, the platen frame is latched in its tiltedposition by the latch to permit ready insertion of the bill and ledger. T he bill is inserted in its guide chutes 78 and SO and is directed by the plate or table 117 so that its lower edge strikes the supporting fingers 127 which have been adjusted so that the printing will be done on the desired line. The ledger sheet is inserted between itspaper chutes 7 9 and 81 and its lower edge is guided by the auxiliary table 129 and the guide strip 145 onto the supporting device 133 which has also been adjusted to the desired position. '1 he proof sheet and carbonare placed on the table 8 and the platen rotated manually in the usual manner. The latch 105 is then released to permit the platen frame to move back to its normal po sition, whereupon the machine is ready for the cycle of operations to print the various As the carriage finally shifts from its first columnar position to its second, the platen frame is tilted back by the cam plate 54 and is then latched in such condition by the latch 105 to permit easy removal of the work sheets while the carriage is in its second columnar position.
